What's the difference between large, medium and small passenger planes?

The specific differences are as follows:

1. Small passenger planes are divided into first class, business class and economy class.

Small passenger aircraft usually fly to the branch line, and the engine room is lifted by propeller or tail. Single aisle, two seats on each side, so the number of passengers is between 20 and 60. The flight time is generally less than 3 hours, so the ride environment is like a bus, no matter first class, business class or economy class.

Medium-sized passenger planes can be divided into first class, business class and economy class.

The definition of medium-sized passenger plane is vague, but it should be a jet high-altitude high-speed passenger plane. Except Airbus A380 and Boeing 747, it is generally called medium-sized passenger aircraft.

Representatives include Boeing 737 and Airbus A330, all of which are dual-engine, single-channel and dual-channel. Generally, these medium and large passenger planes fly in China, and the flying height and speed are similar. There are first class, business class and economy class, but domestic airlines generally set up much more economy class.

Large passenger planes can be divided into first class, business class and economy class.

The most typical ones are Airbus A380 and Boeing 747. They are all wide-bodied and four hairs. Carrying more than 300 passengers. Everything is bigger and more luxurious. Can undertake long-distance overseas routes.

Comparison of large, medium and small passenger aircraft;

1. Advantages of large passenger aircraft: large number of commercial passengers and long flight distance.

Disadvantages of large passenger aircraft: generally used in relatively expensive international routes, the price is expensive.

2. Advantages of medium-sized passenger aircraft: low requirements for airports, short turnaround and maintenance time, and high economy.

Disadvantages of medium-sized passenger aircraft: small number of commercial passengers and short flight distance.

3. Advantages of small passenger aircraft: low requirements for airports, short turnaround and maintenance time, and the highest economy.

Disadvantages of small passenger planes: few commercial passengers and short flight distance.

Supplementary explanation:

1. The difference between a large passenger plane and a small passenger plane is generally in use, length and width. Small passenger planes are regional planes, such as Xinzhou 60, ERJ 190, CRJ200, etc. Trunk airliners are divided into large and medium-sized ones.

2. Large passenger planes are generally wide-body passenger planes, such as Boeing 747, Boeing 777, Airbus A380 and Airbus A340. Medium-sized passenger planes are generally narrow-body passenger planes, such as Boeing 737, Boeing 757 and Airbus A320.

Extended data

A passenger plane is a civil aircraft in a broad sense. Civil aircraft refers to all non-military aircraft. Civil aircraft is also called civil aircraft. Civil aircraft can be divided into two categories according to their respective uses: airline aircraft used for commercial flights and general aviation aircraft used for general aviation. The passenger plane with the largest passenger capacity is Airbus A380, with standard three-class cabin layout and 555 seats.

According to the different classification standards of passenger aircraft, there are the following classification methods:

Depending on the purpose of the aircraft:

There are civil aviation aircraft and national aviation aircraft. National aviation aircraft refers to aircraft used by the army, police and customs. Civil aircraft mainly refers to civil aircraft and helicopters, and civil aircraft refers to civil passenger aircraft, cargo aircraft and passenger and cargo aircraft.

Depending on the type of aircraft engine:

There are propeller planes and jet planes. Propeller history aircraft, including piston propeller aircraft and turboprop aircraft, the aircraft engine is piston propeller aircraft, which is the most primitive form of power. It uses the rotation of propeller to push the air behind the plane, and uses its reaction force to push the plane forward. The higher the propeller speed, the faster the flight speed.

Jets, including turbojets and turbofan jets. The advantages of this model are simple structure and high speed, which can generally reach 500-600 mph; The fuel cost is saved, and the loading capacity is large, which can generally carry 400-500 passengers or100t cargo.

Depending on the number of aircraft engines:

There are single-engine planes, double-engine planes, three-engine planes and four-engine planes. There have been six planes in history, the prototypes of An 225, 1988, 12 and 2 1, and the space shuttle Blizzard, which made its first flight on 1989. Only two planes have been produced so far.

According to the flight speed:

There are subsonic aircraft, supersonic aircraft and hypersonic aircraft. Subsonic aircraft are divided into low-speed aircraft (flying speed is less than 400 km/h) and high subsonic aircraft (flying speed Mach number is 0.8-0.9). Most jet planes are of high subsonic speed.

According to the distance of the plane:

There are short-range, medium-range and long-range aircraft. The range of long-range aircraft is about 1 1000 km, and intercontinental transoceanic flight can be completed without landing. The range of medium-range aircraft is about 3000 kilometers, and that of short-range aircraft is generally less than 1000 kilometers. Short-haul aircraft are generally used for regional flights, so they are also called regional flights. Medium and long-range aircraft are generally used in domestic trunk lines and international routes, also known as trunk lines.

The Civil Aviation Administration of China adopts the classification of large, medium and small aircraft according to the number of passengers. /kloc-aircraft with less than 0/00 seats are small, aircraft with 100-200 seats are medium-sized and aircraft with more than 200 seats are large. The range below 2400km is short, the range between 2400 and 4800km is medium, and the range above 4800 km is long.

But the classification criteria are relative. Aircraft on short-haul routes generally fly from 6000 meters to 9600 meters, and aircraft on long-haul routes generally fly from 8000 meters to 12600 meters. At present, the highest flying height of ordinary civil airliners will not exceed 12600 meters, and some business jets can reach 15000 meters.
